A coextruded biaxially oriented composite film comprising a polyester substrate layer and disposed on one or both surfaces thereof a strippable sacrificial layer, wherein said strippable sacrificial layer comprises an ethylene-methacrylic acid (EMAA) copolymer.

A coated polymer film, such as a coated polyester film, is disclosed. In one embodiment, the coated film may be used as a substrate for digital printing. In one embodiment, the coating contains an anionic anti-static agent comprising a sulphonated copolyester resin. In an alternative embodiment, the coating contains an anti-static agent comprising an organometallic, such as an organo zirconate, in combination with metal oxide particles. The metal oxide particles may comprise nanoparticles. In one embodiment, the coating can further contain a print enhancing agent and an adhesion promoter.

A film for packaging a product that has a pharmaceutical active agent includes a product-contacting sealing layer. The product contacting layer includes at least 90 wt. % of an ethylene norbornene copolymer having a glass transition temperature in a range from 50° C. to 110° C. The pharmaceutical active agent comprises a Hansen Solubility Parameter for the product-contacting sealing layer of 0.5 or greater.

A label for a bottle where the label is comprised of a laminate where an outer layer (3) is a material susceptible to losing opaqueness when made wet, and an inner layer (5) behind this first layer which is a material that is opaque, and such that it will maintain such opaqueness when wet.

A laminate includes the following substantially coextensive layers in the following order: (a) a non-sealable, self-supporting, thermoformable copolyester film layer having a first surface and a second surface, the second surface constituting an outermost, exposed surface of the laminate; (b) a laminating adhesive layer on the first surface of the thermoformable copolyester film layer; and (c) a self-supporting, thermoformable structural film layer having a first surface and a second surface, the first surface contacting the laminating adhesive layer. Polyethylene terephthalate constitutes at least 80% by weight of the self-supporting thermoformable copolyester film layer; the thermoformable structural film layer includes a polymer selected from the group consisting of polyamides, polypropylene, polyethylene, polyethylene terephthalate, ionomers, ethylene acrylic acid copolymers, ethylene vinyl acetate copolymers, polystyrene, ethylene vinyl alcohol copolymers and polyvinylidene chloride; the thermoformable copolyester film layer, the structural film layer and the laminate each shrink less than 5% in length and width upon exposure to boiling water for five seconds; and the laminate is thermoformable and its chloroform-soluble extractives meet the requirements of paragraph h(1) of 21 CFR 177.1630 as defined herein.

A film for packaging a product that has a pharmaceutical active agent includes a product-contacting sealing layer. The product contacting layer includes at least 90 wt. % of an ethylene norbornene copolymer having a glass transition temperature in a range from 50 C. to 110 C. The pharmaceutical active agent comprises a Hansen Solubility Parameter for the product-contacting sealing layer of 0.5 or greater.

There is disclosed an in-mould labelling process for the manufacture of a labelled article comprising the steps of: feeding a labelstock web into a mould; forming an article in the mould such that the formed article contacts and effectively adheres to a label of the labelstock web; detaching the adhered label from the labelstock web; and removing the formed and labelled article from the mould.

A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.

A shrink film comprising a core layer comprising a glycol modified polyester, the core having an upper and lower surface; an upper skin layer disposed on the upper surface of the core layer and a lower skin layer disposed on the lower surface of the core layer, the skin layers each individually comprising (a) a resin material; and (b) an antiblocking agent.

The present invention provides a functional sheet including a functional layer provided between protective layers. The functional layer is a polarizing film layer, a photochromic layer, or a combination of the polarizing film layer and the photochromic layer. At least one of the protective layers includes a layer formed of a resin (C) containing a polyester resin (A) obtained as a result of polycondensation of 1,4-cyclohexanedimethanol and 1,4-cyclohexanedicarboxylic acid and an aromatic polycarbonate resin (B), the polyester resin (A) being contained at a content of 10 to 100 parts by mass and the aromatic polycarbonate resin (B) being contained at a content of 0 to 90 parts by mass with respect to 100 parts by mass as a total of the polyester resin (A) and the aromatic polycarbonate resin (B). A lens is provided with such a functional sheet.
